[0011]

[Action]

 In the light emitting display device according to claim 1 of the present application, when power is supplied to the light source body from the power source, the light source body emits light. Then, the light from this light source is received by each rear end of each optical fiber, and is further separated from the tip of each optical fiber facing the information display surface such as letters and designs on the display plate. It is designed to display various information such as letters and patterns on the display board by light emission.
